13189751 divided by 26 
We want to figure out the number of times 13189751 can be divided by 26.

On to step 1:
The number 26 fits into 1 0 times, leaving a remainder of 1.
Use 0 as the next digit of our solution. 
Result so far: 0.0
The remainder is 1 after subtracting 0 from 1.
Bring next digit (3) of the dividend behind the 1 and repeat the process: 13 / 26

Let's proceed to step 2:
26 goes into 13 0 times with a remainder of 13.
The next digit of our result is 0. 
Result so far: 0.0
Deduct 0 from 13 and we're left with 13.
Take the next digit (1) from the dividend and append it to 13, then repeat: 131 / 26

Let's proceed to step 3:
When dividing 131 by 26, we get 5 with a remainder of 1.
Put 5 as the next digit of the answer. 
Result so far: 5.0
Subtract 130 from 131 to get 1.
Take the next digit (8) from the dividend and append it to 1, then repeat: 18 / 26

Moving on to step 4:
The number 26 fits into 18 0 times, leaving a remainder of 18.
The number 0 becomes the next digit in our result. 
Result so far: 50.0
If we take 0 away from 18, we end up with 18.
Include the next digit (9) from the dividend after 18, then repeat: 189 / 26

Advancing to step 5:
26 goes into 189 7 times with a remainder of 7.
Write down 7 as next digit of the result. 
Result so far: 507.0
If we subtract 182 from 189, we get 7.
Grab the next digit (7) from the dividend, add it to 7, then carry on: 77 / 26

Moving on to step 6:
If we divide 77 by 26, we get 2 and a remainder of 25.
Record the quotient 2 as the next digit in the result. 
Result so far: 5072.0
The remainder is 25 after subtracting 52 from 77.
Take the next digit (5) from the dividend and append it to 25, then repeat: 255 / 26

On to step 7:
26 goes into 255 9 times with a remainder of 21.
Write down 9 as next digit of the result. 
Result so far: 50729.0
Subtract 234 from 255 to get 21.
Take the next digit (1) from the dividend and append it to 21, then repeat: 211 / 26

Going ahead to step 8:
26 goes into 211 8 times with a remainder of 3.
Record the quotient 8 as the next digit in the result. 
Result so far: 507298.0
If we take 208 away from 211, we end up with 3.
Since there are no more digits in the dividend, we add a zero to the remainder making it 30, and continue the process.

On to step 9:
The number 26 fits into 30 1 times, leaving a remainder of 4.
The next digit of our result is 1. 
Result so far: 507298.1
If we subtract 26 from 30, we get 4.
Since there are no more digits in the dividend, we add a zero to the remainder making it 40, and continue the process.

Let's proceed to step 10:
When dividing 40 by 26, we get 1 with a remainder of 14.
Put 1 as the next digit of the answer. 
Result so far: 507298.11
Deduct 26 from 40 and we're left with 14.
Since there are no more digits in the dividend, we add a zero to the remainder making it 140, and continue the process.

The final outcome is 507298.11, with a leftover of 0.014.
